I'm fairly close to 9 to 5 or 6. 3-4 days a week I get up at the crack of dawn to get 2-3 hours in before anyone is up. (It's my best time for uninterupted thinking)

At a prior job it was flipped - most nights a few hours an evening to talk to India.

I haven't had a silicon valley job that encroached on dinner on a regular basis, but part of that is how I selected the firms.
